the likeyit is a Well knownexpedient to employ devices for recbrding-the extent of the coasting travel number of stops' or the duration of stops made by the cars during a complete trip. Any excessive time consumedduring a stop,

"of {the car or train, that brakes are appliedl or "any excessive number of stops made during a trip indicates an interference in and such'interference, of course, affects the operation of'the entire system; -Where a closeheadway between cars or trains is necessary the-interruption of the time schedule of the system due to excessives'tops or excessive duration of stops, becomes a serious matter, and hence the importance and desirability of securing" an accurate record of the number ofs'stops made and 'theduration of such stops, in addition to the coasting time periods, toltheiend that the railway sysa tem may not only be operated economically,

but proper and desirable time or trip sched- However, it is. equally desirable toavoid anytextra OnauXihar-y equipment. It is; therefore, among thespecial purposes of our; present invention to provide an apparatus:

Whichis simple and effective for indicating the @number of stops and the; durationpf stops, and Where a record of the coasting time; is also desired, to provideia combined device, which will 'accomplish both results;

In its essential features, our inventioncon coasting .indicating devicewhich-n'iay be of the usual or Y any Well known type or structure and operated only'when the current is flowing throughit; also a stop'indicating device of suitable. construction, preferably the proper time schedule'to be-maintained,

of the spring motor operated type which is;

electrically controlled in such'mannerthat when ,the flow, of current through the con- 1 trolling circuit is interrupted, said device becomes operative. to"; accomplish its funcclock actuated indicating device shown and described in the Hedley and Doyle patent, No. 1,020,419, dated March 19,1912, might be used in the present system with the present form of control. It is also within the contemplation of our invention to employ the stop indicating device either alone or in combination with the coasting indicating de vice andto provide suitable interrelated circuits therefor in the caseof the combined devices having such relation that when the car or train is in movement, whether operating under the power of its propelling motors, or under coasting condition, or with the brakes applied, the stop indicating device is maintained against operation, while the coasting indicator is operated under the usual conditions of such devices. 7

In carrying out our invention in this respect we provide suitably cont-rolled circuits for the stop indicator to maintain the same out of operation when the car is in movement, current supply to said circuit being secured either from the trolley or other source of power foroperating the propelling motors, when the latterare operating as my tors, or from one or more ofthe motors operating as generators when the power from the supply trolley or other source is cut off. lVealso provide suitable, switches controlled by magnets the circuits of which are completed while current is being supplied to the propelling motors, one of the switches controlled by one of said magnets operating to control the circuit of the coasting indicator and the other operating tocontrol an auxiliary circuit of the stop indicator switch control magnet, both of said switches being opened when the circuit of its control magnet"- is completed and current is flowing therethrough. The auxiliary stop indicator circuit referred to is employed only when the current supply tothe propelling motors is cut off and one or more of such motors is operating as-a generator. The other magnet -cont rolsa switchwhich. is concerned in the control of the stop indicator, and also of the coasting indicator, when the latter is employed, said switch being closed only when the circuit of its control magnet is completed and 'current is flowing therethrough.

Referring particularly to Fig. 1, reference numerals 1 and 2 designate the car or train propelling motors, and 3the usual-controlleremployedin connection therewith, current being supplied from the trolley, third rail or other source 4, in the usual manner. The switch control magnets are indicated at 6 and 7. The armature of magnet 6 operates a lever 9 to which is connectedthe switch arms 13, 14, which, when the magnet is not energized, close upon contacts 15, 16 respectively. The armature of magnet 7, operates a lever 10 to which is connected a switch energization of arm 25, which, when the magnet 7 is ener gized, closes upon a contact 26.

Under normal running conditions of the car or trainwhile operatingunder the motive power of current supplied to its propelling motors 1, 2, as shown in Fig. 5, the magnets 6, 7 are both energized by current in a circuit connecting up said magnets in series, and which circuit includes the lead 5, tapped off from the motor supply circuit, the safety fuses 40, magnet 6, magnet 7 and to ground through circuit connection 8. This energizes both magnets 6. and 7, the magnet 6 causing the switch arms 13, 14,.to open the circuits controlled thereby at contacts 15, 16, while the energization of magnet 7 causes switch arm 25 to close upon contact 26. Thereupon the following circuit is completed. From the current supply side of the motors through wire 5, fuses 40, magnet 6, magnet 7, wire 8, wire 27, fuse 28, switch arm 25, contact 26, wire 41, wire 42, stop controller 21, wire 22 to ground. The flow of current through this circuit holds the indicating device 21 out of action. Under the same conditions the circuit of the coasting indicator 23 is opened. at 13,155, and hence the said coasting indicator is out of action. This is apparent upon reference to Figs. 3 and- 4, where it will be seen, that the spring actuation of the indicating device 21 is inoperative when the magnetis energized, and that of the device 23 is made operative when the magnet is energized. v r r Now suppose that current supply to the propelling motors is cut off and the car or train continues to moveunder its own momentum, whether the brakes are applied or not, the current supply to the circuit of the magnets 6 and 7 is thereupon cut off through wire, 5 and on as above traced. The continued movement of the car ortrain, how ever, drives the motor armatures. Now if the car continues to travel with the current to the motor shut off the motor becomes a generatorof current .as long as the momentum movement of the car or train continues. This principle is well recognized in the-art and is discussed at length in the] atent to Hall and Hall, No. 1,201,041, issue October 10th, 1916., The position of the elements under this condition is that shown in Fig. 1. e have shown the motor 2 as thus acting as a generator, the current generated is supplied through the following circuit. Wire 17, contact16, switch arm 14, these being closed, upon each other since, under the conditions referred to the magnet 6 is deenergized, to wire 32, magnet 7 wire 8 to the other side of the generator. This energizes magnet 7, and closes switch arm 25 upon contact 26, thereby completing the following circuit. From one side of the motor 2, acting as a generator, throughwire 17 contact 15 switch arm 14,wire 32, magnet 7 wire 8, wire 27 fuse 28, switch arm 25, contact 26, wire 41, the circuit then dividing,onc branch continuing through wire 12, stop indicator 21, wire 22 to ground or return to the other side of the generator, the other branch continuing from wire 41, through wire 20, contacts 19, 18 and bridge piece 30, contact 15, switch arm=13, Wire 24,. coasting indicator 23 and onto 'return22. Consequently current continues to flow through the circuit of the stop-indicator 21,-thereby maintaining said indicator out of action. Also so long as the branch circuit through the coasting indicator 23 remains completed at contacts 19, 18, current will continue to flow through said coasting indicator and the same will operate to indicate the coasting time of the car or train. By arranging this branch circuit to be openedwhen the brakesare ap plied the true coasting indication of the car or train will be secured. This result may be obtained by connecting the bridge piece 30 which bridges the contacts 19, 18, to be shifted when thebrake is applied, as for instance by means of plunger 30, so as to open the circuit between said contacts.

By omitting the circuits concerned in the operation of the coasting indicator, and the switch 13 and its contacts 15 and the circuit controlled. thereby, the coasting indicator maybe omitted and only the stop indicator employed.

From the foregoing description it will be seen that we provid'e'an exceedingly simple arrangement for making a record of the number of stops madeby a car or train, and ,p the duration of each stop. lVe also provide 1 a simple arrangement whereby such a device is combined with means to indicate the coasting time of the car or train.

It is to be understood that many variations and changes may readily occur to persons skilled in the art and still fall within the spirit and scope of our invention, as defined in the claims.
